Circular saw blade and process for the production thereof

Abstract

A circular saw blade has a rotary axis and a flat annular body arranged therearound. The annular body has a periphery being provided with teeth. The annular body is of hollow conical shape. For manufacturing the circular saw blade, an initially flat annular body is bolted into a concentric conical support element, thereby deforming the annular body into a hollow conical shape.

I claim: 
     
       1. A method for manufacturing a circular saw blade, the method comprising the steps of: providing a planar, flat annular member having a periphery and being provided with teeth therearound;   providing a support member having a central mounting flange and a concave conical support surface therearound, said conical support surface having a cone angle of approximately 1°;   rolling said annular member along concentric circular tracks while maintaining its planar shape;   inserting said planar rolled annular member into said support member to adjoin said concave conical support surface; and   bolting said annular member onto said concave conical support surface while simultaneously transforming said annular member from its planar shape to a conical shape corresponding to said concave conical surface shape.
